Re: AMD Catalyst™ Control Center / AMD Vision™ Engine Control Center 11.8 Driver Pre
is it possible to watch DVDs via Windows Media Player on Windows 7 with these drivers? with previous drivers I had problems... *lock ups*
AMD Catalyst™ Control Center / AMD Vision™ Engine Control Center 11.8 Driver Pre
FTFY
Edit: Oh, wait, somebody already pointed that out. I didn't know they did because it was stuck in a fricking picture, which didn't load the first time I loaded the page. Picture Fail, shoulda used text.
Re: LQC (Liquid Coin) -- Another Virtual Currency to increase liquidity
ahhh... no.
the thrust of yourargument post is this:
which boils down to the usual IT'S NOT FAAIIIRRRR!!!
but it is. you just weren't smart enough, on top of stuff enough, or courageous enough to take the risk and devote the time and effort.
neither was i.
but those who did deserve everything they get - and i'm quite content to ride their coattails. why aren't you?

LQC (Liquid Coin) -- Another Virtual Currency to increase liquidity
so with the ever increasing difficulty of BTC mining (starting to slow and perhaps may level off and eventually decrease,) and the less popular NMC mining situation (involving high difficulties lately driven by BTC hoppers trying to make a quick buck from massive drops in difficulty) there seems to be a need for more than just 1 or 2 virtual currencies to help with liquidity in the markets... if we had more virtual currency options it would give hope and more speculation for high earnings due to very low difficulty from starting up...
but the one variable that seems to be haunting is the massive hopping around which skyrockets the difficulty...

I proposed creating the LQC or Liquid Coin for the sole purpose of increasing liquidity for all currencies based on some intuition

Researchers in Germany released a pair of papers documenting severe power analysis vulnerabilities in the bitstream encryption of multiple Xilinx FPGAs. The problem exposes products using FPGAs to cloning, hardware Trojan insertion, and reverse engineering. Unfortunately, there is no easy downloadable fix, as hardware changes are required. These papers are also a reminder that differential power analysis (DPA) remains a potent threat to unprotected hardware devices. On the FPGA front, only Actel seems to be tackling the DPA issue so far, although their FPGAs are much smaller than Xilinx's.

This could be the last version, because there seems no more room for big jumps. I thought I could remove some more additions, but the OpenCL compiler does a better job than I
. This version is faster than all previous kernels (uses the least ALU OPs for 69XX and 58XX). Should also work with SDK 2.1. If it throws an error with 2.1, please post here and include the error message!
Thanks to all donators and your feedback!

This one seems to act rather strangely.
On 2011-07-06 I had a pretty consistent 360MHash/sec with little variation. With 2011-07-11 the card is varying dramatically between 355-363, and usually at the lower end of that. Overall it may be slightly slower.
The cards are 5850s clocked at 900/300, using 11.4 and SDK 2.4 on Linux.
I'm going to let it run a while longer.
Sorry, but this is still slower; my cards were running around 355MH/sec and even down to 350. Went back to 2011-07-06.
I totally disagree, each version for me has been getting faster and faster. 7-11-11 is the fastest, yet for me.
make sure you all disable ULPS when in CrossFire/X mode... and using anything like MSI Afterburner, because ULPS enabled (i think by default) tends to power off one of the cards in CrossFireX which will crash out the whole system when applying settings via apps like MSI Afterburner
Re: New scalable pipelined FPGA core for SHA-256 - any interest?
I've got a Stratix IV dev board (the GX 230 model) that I'd try your code on. It seems like the mining program is where more of the inefficiencies lie. I'm running @ 240MHZ and two cores and getting around 200-300 Mhash/second.
Using OrphanGland's code and fpgaminer's mining program.

did you try overclocking it to 500MHz that it supposedly supports?
You know that you don't need the crossfire bridge for mining right?
Crossfire hurts your performance when mining. People use dummy plugs because they have no choice. When I had 4x crossfired it was constant problems.
I call BS on this one. It is very hard to believe that this 4x sandwich does 0.4 Ghps per core for more than 1 minute in a row. Maybe with exception of some weird setups with room refrigerated otherwise and even than it is highly doubtful.
Video on youtube or this is a fake.
i am running 2x 6970s @ 905MHz/170MHz gpu/vram respectively, and they push 401Mh/sec each...
